What is Materials in Year 4 Science (KSSR)?
The materials we use every day come from three basic sources: plants (cotton, rubber, wood), animals (wool, leather, silk), and petroleum (plastic, synthetic fabric). Each material has unique properties such as strength, flexibility, water permeability, and heat conductivity that determine its use.
